Troy Polamalu wanted to return to the West Coast to be near his family when his contract expired after this season, or so rumors have had it. If so, he will return for visits only. Polamalu, the most unique strong safety in the NFL and among its best, has come so close to a contract extension with the Steelers that sources close to the negotiations believe he will sign a new deal around the opening of training camp Monday. Terms of the contract were unavailable but it likely will put him near the top among the Steelers' best-paid players.
